ECS Ejector Automatic Air Vent

This FM Approved product provides automatic venting of trapped air in wet pipe fire sprinkler systems that effectively addresses venting requirements in the 2016 edition of NFPA 13. Trapped air contains oxygen which is the primary cause of corrosion in sprinkler systems. As a fire sprinkler system is filled with water, trapped air migrates to the high remote portion of the system where the vent is located, releasing the air.
